Using RuleSets in Workflows

A RuleSet consists of one or more rule conditions and their resulting actions. You can think of a rule as an IF-THEN-ELSE statement, with the condition corresponding to the IF, and the actions defining the behavior of the THEN and ELSE clauses.

An action can do the following:

• Set a field or property on a workflow.

• Call a method on a workflow or objects in a workflow.

• Call static methods on types in referenced assemblies.

• Perform a Halt or an Update statement.

• The Windows Workflow Foundation rules engine is designed to run rules in a priority-based manner with support for forward chaining.
